A Unique Natural Coir Storm Drain Filter

Coir Drain CoverOne of GEI Works' many coconut coir products, the coir drain cover is an excellent solution for sediment control during the construction phase of work sites and project areas. Rated for NPDES II compliance, these coconut coir filters come in pre-cut sizes that can be field-sized using only shears or a utility knife.

With a filtering efficiency of 59.1% and a flow rate of 150 liters/minute, the natural fiber filters allow water to drain while stopping sediment outside the grate. They install quickly without requiring grate removal and can withstand heavy vehicle traffic. These natural coir filters can fit a variety of storm drain inlets:

Storm Drain Filter Installation

  1. Clean the Area – All the debris and sediment around the drain needs to be cleared out, so you can start with a tidy space.

  2. Put in Place – Make sure your coconut coir pad or roll covers the right area. The coir drain cover should extend at least one inch beyond the front and both curb ends.

  3. Insert the Zip Ties – Once the piece is verified and in place, connect it to the drain without lifting the grate cover. Push the zip ties through the coir drain cover to loop around the grate bars and back through the inlet filter. The space between the in-and-out points should be about 2 inches.

  4. Tighten Zip Ties – Once all the zip ties have been inserted, looped around, and loosely attached, double-check the positioning of the pad. When you're sure of the placing, tighten the zip ties and cut off the ends, leaving a 1 inch tail. The storm drain filter is ready!
